` same time contain the maximum amount of metal for a generally cylindrical upright body within given side and height cl'earances.

In accomplishing these objects, under or side frames are eliminated, thereby adding considerable carrying Capacity. To Carry the pulling and pushing stresses occurring in moving the car on the track and also the dead load, the frame connecting the wheel trucks is designed as a body section with elongated trunnions, each having two bearings cooperating with similar bearings on end; platforms, the platforme being supported and pivoted on the respective trucks. The body .comprises generally an upright cylinder with top pouring spout and closed bottom and is rotatably mounted. Thereby, thebody can be tilted either by a crane or by motor power, as may be desired. The body preferably consists of a bottom dished only s'ufiiciently to provide necessary wheel and track clearance, the central cylindrical section carrying the trunnions, and a top of substantially a cylindrical segment With such a body, complete discharge of metal is provided when tilted without pouring on or within the track, and with maximum content within given dimensions.

In the accompanyng drawings; Fig. 1 is a side elevation partly in section of the hot metal car embodyng the invention;

Fig. 2 is a top plan view of the body; and F ig. 3 is a transverse vertical sccton. i 1-1 represent trucks having pivoted thereon end frames 2-2. The bodies have hearing pedestals 3-3 in which are mounted elongated trunnions 4-4 supported m separated bearings 5-5.- The end frames 2 are j ournaled on the trucks in the usual manner with usual king pins and side bearings and coupling. Draft gear, etc., is not shown. Trunnions 4-are connected to a cylindrical ring 6, which constitutes a portion of the mid- 1929. Serial No. 3573589.

dle section 'Za of the body 7. The body 7 carries bottom section 8 and top section 9 with pouring spout 10. 12 is the refractory lining, which can be made of standard shapcd bricks instead of specially shaped bricks, owing to the' particular features of design described below.

As'shown herein, the body can be dumped by a motor Operating on the trunnions through reduction gearing of suitable design. If desired, the reduction gearing can be operated by hand, and if the motor and reducti-on gearing are not to be used, the body can be provided with lugs 15 for attachment of a dumping crane hook. Draft and compression stresses are transmitted between end frames 2, pedes'tals 3, trunnions 4, and body 7 as a unit. The inner bearings 5 are shoulderedon each side to act as thrust bearings. The axis of the trunnions is above the center, of gravity both when loaded and when empty, so that the body will right itself as in case of breakage of the tilting mechanism.

i As the body has to be tilted in the car and a certain clearance between the track and wheels must be maintained, the bottom secton 8 is made as a segment of a sphere having a radius equal to the distance from the trunnion center to the bottom clearance line. Thereby, the minimum required clearance is maintained at any position of the body, and also maximum cubic contents. The central portion 7a is a cylindrical section which is made as long vertically as possible within= permitted Master Car Builder@ or special clearances. The top section 9 comprises a segment of a cylinder whose axis is horizontal and parallel with the trunnion axis, so that the top section and central portion comprise the intersection of two cylinders having their respective axes in planes at right angles to one another. The radius of this top cylin-- drical section can vary with the hei ht clear- -ance of the body, but a practical ra ius is the distance' from the trunnion aXis to the maximum height clearance line, less the height of the central spout 10 above the uppermost portion ofthe top cylindrical section. In-

stead of one central spout, a separate spout on each side can be used. All' three sections can therefore be easily lined with standard' forms of bricks, and on account of the generally cylindrical shape have a large cuhical content.

The spout opening at the top is usually 5 x made as small as possible and yet permt entrance and exit o f men to line the ladle. I do not restrict myself to use of three sec.- tions, as' a ladle and body embodying this m invention can be made in one or twosections and of cast or plate metal. .Also, I do not restrict myself to the specific trunnion and body structure herein described as same can be modified in various parts without departing from the scope of the appended claim. The invention claimed is: In a vertical type -hot metal car, a, multisection 'body comprising a dished bottom, a central cylindrical section joining said dished bottom at one end, a top cylindrcal section joining said central cylindrical section at its other end, and a spout on the top section, said top section having its aXis in a plane substantially at right angles to the planes of the axis of the 'central cylindrical section, the sides of said spout lying within a projection of the walls of the central cylindrcal section of the body and the u permost portion of said spout lying closely ajacent to a plane perpendicu- ,30 lar to the axis of the central cylindrical body section and assing through the intersection of the axis o the central cylndrical body section with the cylindrical portion in which the top cylindrical section of the body lies.
